Polarization imaging screen using vector gratings fabricated by photocrosslinkable polymer liquid crystals, H. Ono, T. Wada and N. Kawatsuki, Jpn. J. Appl. Phys. 51 (2012) 030202.


We demonstrate a polarization imaging screen using vector gratings by ultraviolet laser direct writing of polarized-light-induced optical anisotropy in photocrosslinkable polymer liquid crystals. For realizing a polarization-sensitive diffraction in the image screen, spatial distribution of the optical anisotropy has been designed, and the right- and left-hand side circularly polarized optical image are clearly reconstructed as the +1st and -1st-ordered diffraction according to the theoretical expectation.
